: Established in 1945, this old-fashioned coffee shop seems to appeal to just about everyone on Palm Beach Island, from society ladies to blue-collar laborers. Proprietress Cynthia Rosa took over the Palm Beach institution in 1990 and gained a reputation for her eggs with grits and hearty burgers (including vegetarian and turkey versions). For even more nostalgia, sip one of Hamburger Heaven’s root beer floats.
